I grew up thinking teddies/stuffed animals came awake when you weren't there and played together in your room until you came back when they quickly laid down pretending they weren't really real. Even now I find it hard to treat them like any other toy that gets thrown in the toy box and like to make sure they are comfy IYSWIM. I do realise this makes me slightly soft in the head!
Anyway my 3 year old quite often tells me his teddies aren't real eg if I tuck him into bed and say are you comfy he says yes, I say is Bear comfy he says don't be silly he's not really real. Or I say don't throw Bear down the stairs you'll hurt his head he says he can't hurt his head he's not real!
Is it normal for kids to be this practical about things? Every time he says it I feel sad both for the bear and for him. OH thinks I'm mad, am I?
